I know many police officer that hated to give up their 357 Magnum revolvers, when their departments went to a semi-auto handgun.

The 357 Mag has a outstanding reputation for stopping a bad guy! The 125 gain hollow point traveling around 1,400 fps. was one of best, if not the best defensive handgun rounds produced.

Since the 357 Sig also has a 125 grain hollow point traveling around 1,400 fps. does this make it just as effective as the 357 Magnum?

The .357 sig. bullet is actually a .355” diameter (9 m.m.) so its pretty close diameter wise. I am still working up hand loads for my P226, and my Lyman book lists 1400 fps as about the maxload for a 125 gr. Speer Gold Dot, depending on powders, I’m still down in the 1200-1300 fps range, but still a fast bullet.
Interesting question though, My Ruger Blackhawk .357 mag has a helluva lot more recoil than my Sig P226 .357 sig. I guess a range report is in order, as I have never had them both out at the same time.
Thanks for the idea, maybe next weekend:)

Yeah , I’ll still try it Shihan, even after posting to a 3 year old Glock thread, Funny Stuff:eek:
I was just going to shoot steel plates though, and see which did the most damage, I think I know that answer already though:)

O.K. I,ll have to load some 10mm, cause I can't find them in the store.
Might take a little longer for a range report!

I realize this thread has been necroposted but the 357 Sig can be nearly as effective as the 357 Magnum, it just depends on the loads. The 357 Mag will always beat the 357 Sig in flexibility because you don't have to worry about cycling and possibly damaging a semiauto - where a thick framed revolver can take more abuse.

But the semiauto loads can get real close and will be softer shooting than a revolver due to some of the recoil being used to reload and cock the action. Either is a fine choice, get both! :D
